Scanning electron microscopy was used to examine achene epidermal features in species of Carer section Mitratae and the allied section Acrocystis found in Turkey. Members of section Mitratae share a particular achene phenotype. Micromorphological characters appear to be conservative, and show little variation between species of section Mitratae. Comparative data of achene micromorphology support the placement of C. tomentosa within section Acrocystis.
